To all whom it may, concern: Be it known that-LI, MArHrAxs LAUX, a citizenot the United States, residing at Little Rock, in the county of Pulaski. and State of 'I have invented af Carburct'er, of

buretersgand/ relates more especially to appPr-atusof; this vc'liaracter which are emiofnloyed' in connection with a domestic plant or producing carbu-rated. air for heating,

illuminatingpurposes.

` The primary-object of my invention is to pnovide-.a carbureter tank ofiv improved conpasslng through or gasolene inl proper proportions soas to produce a. mixture electivepfor domestic pu oses. y inventionoonsistsin thefprovisson of certain means -tor distributing the, hydro,

carbonor gasolene in such manner that it' wlllthononghly'mix. with the airlas it passes through thevtan-k from: onev end to the other, and more articularly tothe devices vf or supportingA fa ric diaphragme adapted to hold `some of: the hydrocarbon. or -gasolene in susy pension.

My invention cnsists further in the particularconstruction and. arrangement of parts; all. as will. be hereinafter fully describeda'ud. specifically set forth the appended claims.

'In 'the accompanying drawings, .which this .specificationrs-Figure 1 1s a vertical longitudinalfsectional view of a carbureter constructed in accordance with .my present. invention. Fig. 2 is a detail sectionalview of the-upper. end of the tank, showingthe application thereto of a closing' ca hereinafter referred to. Fig. 3 is a deta I plan view of a spreader employed for distrlbuting the hydrocarbon or gasolCne upon its discharge in the tank. Figs; 4 and `45- 5 are detail views of the means forsupporting the fabric and netting diaphragme the i v netting-being broken away inl? 5 to show the connection of the binding wire to the s llt-ring. Figs. 6 and 7 are detail views,

A 5.0 i ustrating a modification of the supporting `rneans for the diaphragme.

"Like numeralsv of reference indicate like piirts in all the gures of the drawings.

In carrying outmy present invention l emploiyacylmdrioal tank l, whichis.

at an angle as shown so as todrain to one atits lower end by `bottom platey 2, disposed side of the tank and into a drain-pipe 3.

Sh'rnnk upon the tank, or otherwise secured thereto, at the uppenend thereof, is a ring 4, having an outwardly-projecting iiange'4 5 through which pass bolts 6 for attaching to capll (Fig. 2), a washer, 12., being provided within the .cap to .insure ar tight joint.

'- `Disposed within the upper part ofthe tank1 and secured at its edges between the llanges v5 and 8 is a flexible dia hragm 13, which l Vterni` an equalizer, aid preferably composed ofraw-hide. This diaphragm or equal izer is provided centrally with a. weight 142,

from which rises a rodl adapted to normally 'project through the o ening 9. As will be seen, the upper end-o' the tank is closed or sealed by means of the raw-hide diaphragm or'equalizer, and when the latter isin per feetv condition the rod 15, which projects `vthroughthe opening in the dome will indicate the varying pressure within the tank. The

oflice of this diaphragm is not vonly to indicate thefvarying pressure Within the tank, butalso serves to equalize or take up for pressure when the capacity of the tank is suddenly drawn upon, ashereinafter explained. In case this diaphragm should leak from any causethetop of the tank may be sealedby applying the cap 1:1, whereby the tankmay be continued in use until a new diaphragm can be cnveniently installed.

An air pipe, as 16, enters the lower end of the tank a slight distance above the bottom .2, and a service-pipe, 17, leads from the upper part ofthe tank, while disposed within the tank between the pipes 16 and 17 are 'fab'- ric diapl'n'agins 1S, spaced apart and cut away at opposite ends alternately so as to provide a circuitous pas :ige from the air inlet i e to the serviceii )e and a nettino' or wire screen 18a beyond the end of each fabric diaphragm, said diaphragms receiving the hydrocarbon or gasolene from a discharge pillage 19, connected to a feed pipe 20.

j' yor the` purpose of distributing the hydroroo through the same.

carbon or gasol'ene discharged from the pipe 19 I provide a spreader device 21, consisting of radiating troughs 22,'having perforated bottoms and thickened end Walls, as shown Ain Fig. 3 of the drawings. This spreader deviceis securely held in place Within the tank by means of set-screws 23, which are threadedin the thickened end Walls and bind or impinge against the inner wall of the tank; said s reader also serving to hold in place the dia- `p ragm supportshereinafter described.

As shown 1n Figs. 1, 4 and 5, the fabric and netting diaphragms are'supported by means 1en ds of the latter. In placing the rin and diahragms confined thereon in the tan the en of the ring are lapped. one over the other, so as to decrease the diameter of the ring, and after it is placed in the tank the eX- pansion of the ring will cause the retainingwire to press upon the fabric and netting and hold them tightly in place, it being understood that the outer ed e of the wireis on a vertical plane slightly eyond theplane of the outer edges of the fabric and netting. In applying the ring the inwardly-projecting en s of the retaining wire provide a convenient means for handling the saine. The lower diaphragm support rests upon lugs or brackets 27, and the others are stacked thereon, as shown in Fig. 1 of the drawings, the stack being confined by means of the spreader 21 which is secured in place by the set-screws 23, as hereinbefore described.

I prefer to locate a dia hragm above the discharge end of the nozz e which feeds the hydrocarbon or gasolene into the carbureter, and so as to prevent the liquid from being freely drawn into the upper part of the tank and into the service pipe when the, capacity of the tank is suddenly drawn upon. This dia hragm, 27 a, extends entirely across the tan and is preferably made of a coarse fabric so that the carbureted air may pass In the preferred form of construction of the support for the fabric`diaphragms, and as shown in Figs. 4 and 5, the ring is made 0f metal. However, I also purpose to make the ring of wood, and also form the -binding ring or band of wood, such a modification being shown in Figs. 6 and 7. In this instance the.

wooden ring or hoop, 28, is grooved leaving. outwardly-projecting flanges 29, and in order to bend the Wooden strip into the form of a hoop these flanges are rovided with sawkerfs, as is usual. With t is ring is employed vice so that sealy/'a a plain woodenhoop 30, which binds around the peripheryl of the hoop 28 and secures the edges of the fabric in a manner similar to the retaining-wire 25.

The feedipe f or the hydrocarbon or gasolene is provided with Aa coupling-device 31, having a glass front 32, and the end of the pipe which leads from the supply-tank `or force-pump terminates in this coupling dethe flow of liquid can be seen. The operation of the device will be readily understood by those skilled in the art to which it relates,.for the air in passing through the tank from the inlet pipe 16 to the outlet or service pipe 17 takes a cireuitous passage around the fabric diaphragms and through the netting thoroughly gasolene that drips down through the tank from diaphragm tol diaphragm; the. spreader in connection with the particular arrangeor wire-screens and is thereby charged with the hydrocarbonor ment of the fabric and netting diaphragms distributing the volatile liquid so thatv it will be readily taken up by the current of air and form a richmiXture suitable for illuminating and heating purposes.

Having thus described my invention, what I claim as new and desire to secure by Letters-Patent, is

1. A carbureter, comprising a tank having a dome-shaped' head or cover with an openii at the center thereof, a threaded collar sur rounding the opening, a diaphragm secured Within the tank immediately below the head orcover,` a weight on the diaphragm having a rod extending through the opening vin the l head or cover, and a cap adapted to be threaded on the aforesaid collar and close the opening in the head or cover of the tankgtogether with an air-inlet, an outlet, a discharge-pipe and means porarily in suspension as it passes down in the tank.

2.
